M/T Sportsman pro tyre growth

[Viva632]

Hi,
Anybody have an idea of how much M/T Sportsman pros (33 X 19.5) grow at speed? ie, approx. what sort of clearance do I need in the wheel tubs? (ignoring suspension travel..)

have used these for ages and growth is negligable.certainly no where near as much as a slick tire.how much room do you have?

Hi Dave, I'm building the car from scratch, so I can build as much clearance as I like, but the less clearance I need, the lower the body can be... I've heard of 4 inches needed for slicks, but never seen any figures for M/Ts. What sort of MPH are you running?

i have run 9.9 @ 137 on mt pro's,but have spoken to colin lazenby who as you know runs alot faster than that and he also reports no significant growth, so go low!
